Lichens at Ashcombe Bottom, between Brighton and Lewes. A relict of ancient South Downs forest 01.04.21

Ashcombe Bottom, 4km west of Lewes, is one of the very few ancient woodlands left on the East Sussex Downs. ... the hazel coppice supports a colony dormice - an exclusively arboreal rodent - to which for millennia this wood must have been a kind of ark in an ocean of open fields. Among the hazels grow many spreading oaks, their branches festooned with polypody and harts tongue ferns. Oaks dislike chalk but thrive here because the acid clays deposited on top the chalk have not been dispersed by ploughing or erosion.Owen Johnson (1998) The Sussex Tree Book p.24.
